Beitl known ,that I, JOHN rHENRY 'GATELY, a citiien lof the United States, residing at BelloivsFalls, in the county of Windham and.

State of v Vermonthave invented -a -neW and l usei'ul lVindinU-Core, of which the following This invention' is aspeciificatifn; w L

Y 'relates 'to Winding-cores for the l'support [of roll goods, particularly for use in connection With paper-making vnfia'chiiies to have the paper `Wound' thereon it cornes from the machine.

soon Wears the saine, which impairs the conneetiombetween the drive4 element and the core. Furthermore, the torsional strain upon the core tends to crack the same, Wherefore the life of 'such cores' iscOmparatively'shoi-t..

Having appreciated the foregoing objections, I propose. to obviate the same in a simpleand novel 'manner byape-culiar reinforcing] oi? each end of the core, so as tobrace lthe ysanne against? torsional strainand also to take the wear of the pin or key carried, by the' drive element, thereby to maintain the most eective connection between the fdrive element and the core and to materially prolong the life of the core.

YVith these .and other object-s in view the present invention 'consists the comb-inw tion and arrangement ol' parts, as' Will be hereinafter more fully described, shown in the accompanying drawings', and .particularly pointed out Iin the appended claims, it

' being'tiriders'tood that changesin the form,

proportion, size, and minor details may be made Within thenfbepe ofthe claims Without from the spirit` or sacrificing any of 'the advantages of the invent-ion.

.inthe accompanying drawings, Figure 1 is a fragmentary sectional view of a tubular core the reinforcement of the present' invention applied thereto, al conventional forni of drive element being shown in dotted lines.' Fig. 2 is a ldetail perspective /view x Specification of Letters Patent.` i@ ...1 fippiimion ned october 2s, ieoaxserai Naas/1,067.

' In Fig. l of the drawnigs` there has' been' shown a fragment ary end portion l of acon` ventinal 4Winding-core as 4employed iii con neet-ionz With papeninakiiiginachines` oeivingand lstoring the"paper",asji,J` yproduced by the machine. kSuch core's'are tubuzlar and open-ended, .andfsvliileftlieymay oe formed ofany material.' they lare usually -made of paper, sov .as to "befcon'i'paratively liglitand 'atthe same timepossess sufiieien't .strength and durability. l` coreis oidii'iarily drivenzi'roin `a cylindricaldrive element,i such as indicated in dotted lines and designated 2, the reduced extremity oflwliiclh is intro duced into the adjacent open end fof the .core and providedwitli a radial projection or key 4, adapted to take into a notch in the end of the core, so as to interlock theseelements for simultaneous rotation. llt4 is obvious that 4the projection or key t'Wea'rs the walls of the notch and the torsional strain tends to crack thev core. These objections are overcome by the employment i of the present reinforcenient, which consists 'of concentric spaced inner 4and/outer .sleeve members 5 and/'6, which are terminally connected? by'an integral annular ring or Web 7. The end of the core isfreceivedbetween the sleeve members 5 and `6 and is provided with the external and internal annular rabbets Sand 9 for the or key 4 ofthe drive element 2, whereby the latter bears against arnetallic surface instead of againstvthe material of the core, `Which prevents Wearing of the core by the pin or ey. Moreover,` as-the end of the core is snugly embrac d between the .sleeve mem# for rereception of said sleeve members, whereby IOO bers of thelrei orcenient element fit isstiif- .i

ened and strengthened,` andthe reinforcing element takes the .torsional strain, and thereby 'prevents splitting` and cracking of the core.l

eled, asshown at 13, so as to bear against the -annular beveled portin le of vthe drive ele-. ment7 whereby a 'Wedging action ishad between the drive element and the reinforcing element, which 'constitutes a connection between'these elements in addition to the connection afforded by the pin or key 4, fitting in the seat or notch 12.

im ortant feature of the present ide? vice resi es in the fact that the seat 12 inter-,

'sects the ,outer periphery of the device,

`whereby` Vthe devicewill accommodate the key 44 even though the latter may be longer r thanthe Width of theseat.

A From the foregoing description it will be understood that the. reinforcing element of i thel presentv invention *may be applied to any ordinary tubular core Without making any material change -therein beyond producing the inner and outer rabbets for the reception pin orkeycarried by the drive element, and

therefore no change in the drive connection l is necessary.

Having onus described the invention, what is claimed is- 1. A tubular Winding-core having annular recesses in the Vinner and outer faces thereof .at one end, the' inner recess extending farther into thecore than-the outer recess and the end of' said core being smooth and uiiinterrupted,` a sleeve fitted within the outer recess, means extending therethrough. and into the core for fastening the-sleeve upon the core, a sleeve the innerrecess and extending vbeyond the inner .edge-of the outer sleeve, a web connecting the-s A eeves and bearing upon the end of the coresaid`web having-a keyreceiving seat extending thereinto.

2. A reinforcinglatt'achment for winding# cores comprising inner and outer concentric sleeves having a connecting-web at one end, saidinner sleeve being longer than and projecting beyond one end of the outer sleeve, and saidweb having a key-receiving seat extending intoV the outer -face thereof and intersectiiig .the inner andV outer peripheries of the reinforcing attachment. 4 l

,In testimony that I1 claim the foregoing-as my own I have hereto afiixed my signature in the presence of two witnesses.
